WASTE-VALVE-OPERATING momma;

I Application filed Ju1y 5, 925. s am. 203,340. v

v The present invention relates to waste "valve operating mechanism andhas for an object the provision of means whereby the .waste or drainvalve of a bathtub, wash basin; lavatory orthe like" may be alternatelyoing a hand piece.

A further object is to provide a simplified and sturdy mechanism forcarrying out-the above object and, in which the only part of the,mechanism. disposed above the tub," basin orthe like is the hand piecewh1ch is pushed to open thevalve and pushed to close the same.

An additional object is to provide a. mechanism as above described withmeans for restoringthe hand piece to its. original position after eachoperation.

Other objects and advantages will become apparent from a-considerationof the following description taken in connection with the accompanyingdrawing wherein Fig. 1 is a vertical sectional view showing theoperating mechanism in its relation to the drain valve;

Fig. 2 is an elevation showing the hand piece and parts directlyassociated therewith;

Fig. 3 is a detail sectional view showing the operating cam in itsrelation to the valve stem; and

Fig. 4 is a detailed View looking from the bottom, showing the clutchmeans for imparting a quarter turn to the cam on each manipulation ofthe hand piece.

Referring in detail to the drawing, 5 in dicates a wash basin which isprovided with a drain opening 6 and an overflow opening 7. Arranged inthe drain opening 6, is a bushing 8 flanged at its upper end as at 9 andthreaded at its lower end into a fitting 10. The bushing 8 secures thefitting 10 to the under side of the wash basin and has secured to itslower end a drain pipe 13.

WVithin the bushing 8 is the valve including a head 11 arranged to fiton the flange 9 of the bushing for closing the drain. A spider 12 formspart of the valve and guides the same to insure proper seating of thehead 11. On the lower end of the valve there is adjustably fitted athreaded stud 13 for a purpose to be described.

Mounted in the flange 14 of the wash basin is a tubular sleeve. 15through which slidably extends a vertically disposed rod 16 having itsupper end threaded into a pened and closed by siinply pushmetal bushinglTembedded inahaiid piece.

18 of porcelain or the'like- Within the sleeve .15 and about the rod 16is a coil spring 19. This spring bears at onev end aga nst the bottomofthe sleeve and at its upper endbears against the hand piece '18.

The spring'serves" to restore and maintain the parts in their normalposition as 'seenin Threadably connected to the loweriendof rod 16,' foradjustment is a'yokeQO, adjam tion the yoke is provided with averticalslot 22 and ajhoi'izontal slot 23. x

raised and lowered owing to the fact that the stud 13 remains always incontact with the cam.

Mounted on the outer end of the shaft is a collar 29 fixed to the shaftas with a pin. The-centrally grooved portion of collar 29 is receivedwithin the vertical slot 22 of the yoke to act as a guide but to permittree vertical movement of the yoke.

oLikewise mounted on shaft 27 to turn therewith is one element 30 of aclutch ele ment the other element 31 of which is mounted on the shaftfor movement relative thereto. Element 31 is hollow and a coil spring 32arranged therein presses at itsre spective ends against the collar 29and the element to maintain the elements 30 and 31 in engagement.

, A projection 33 on the element 31 carries a pin 84 which operates inthe horizontal slot 23 in the yoke 20. To maintain the element 30 inposition, a spring pressed plunger 35 is arranged to engage in notches36 in said element.

In the operation of the device, assuming the parts to be in the positionshown in Fig. 1, and it being desired to open the valve it is butnecessary to push downwardly on the hand piece 18. Such action resultsin a downward movement being given the yoke 20 and owing to the pin andslot connection between the yoke and element 31 such element is given aquarter turn. Any turning movement thus delivered The fitting 10 has atubular extension 24 provided with bearings 25 and 26 for a shaftposit-ion.

causes a corresponding movement to be delivered to element and thence toshaft 27 resulting in a quarter turn being given element 31 to theirformer position the arrangement of teeth on the clutch elements and thespring 32 permitting this.

When it is desired to again close the valve it is but necessary to pushthe hand piece to give a quarter turn to the, cam moving the same to letthe valve descend to closed Having thus described the invention what isclaimed is: v

1. Means for operating a valve, said means including a hand piece, ashaft, a cam on said shaft and in contact withsaid valve, a rodconnected with said hand piece, a yoke adjustably connected with saidrod, means for maintaining said hand piece and rod in normal position, aclutch on said shaft and comprising a pair of complementary members oneof which is secured to and the other of which is turnable relative tothe shaft, means normally maintaining said elements in clutchingengagement, means'for maintaining said shaft against casual movement,and a pin and slot connection between the yoke and turnable clutch meansincluding ahand piece, a shaft, a

cam on the shaft, and in contact with the valve, a clutch on said shaftandhcomprising a pair of complementary members one of which is securedto and the other of a which is turnable relative to the shaft, meansnormally maintaining said "elements in clutching engagement, meansengaging one of said elements and maintaining the shaft against casualmovement and means for imparting a partial turn to said clutch elementsand through them to the shaft and cam to open and close the valve onrepeated depressing of the hand'piece.
